Funny how weeds are just something growing where you don’t want them. When I had my field reclaimed the top layer of soil ended up in the stump pile. That was in 2009. I limed and tried planting various cover crops but they didn’t do well. (The turkeys didnt help matters any) For the next few years though I had a bumper crop of daisies and Black eyed Susans. They have pretty good sized root systems and over time did a good job of aeriating the soil. After a few years grass started growing, and the soil started to become fertile. I’m even starting to see earthworms, which I haven’t had since I bought the place in 2002. Funny thing though, I have no more daisies or Black eyed Susans.
